Kombucha on Tap vs Bottled Kombucha
For any operator selling kombucha by the glass — cafes, taprooms, juice bars, wellness studios — draft kombucha wins on COGS, speed, and waste. Bottles only beat it when you're selling to take home.
Draft kombucha runs at 50-70% lower COGS than bottles, hits 75%+ pour margin at retail, and ships in one keg instead of cases. Bottles still beat draft for retail shelf sales and gift packs.
Kombucha Kegs vs Bottled Kombucha: what actually matters
Bottled kombucha built the category, but it's a packaging format optimized for grocery shelves, not for pouring. Every 16oz bottle a cafe pours costs $3-$5 wholesale and yields about $7-$9 retail — a roughly 35-50% margin once you factor in chill space and breakage. Draft kombucha in a 1/6 bbl Sankey D keg lands closer to $1.50-$2.50 per 12oz pour wholesale and clears 75%+ pour margin at $6-$8 retail. The tradeoff is operational: you need a kegerator or jockey box, a CO2 line, and a regular customer base to move through a keg inside the 30-60 day tapped window. For any venue already pouring beer, coffee, or cold brew, the equipment investment is essentially nothing — you just add one tap. Below is the per-pour math, the side-by-side comparison, and when to pick each format.

Which should you pick?
Choose draft kombucha when
You sell kombucha by the glass and already have (or can host) a tap setup. Cafes, juice bars, taprooms, gyms, and yoga studios with a beverage bar will recoup the equipment cost within 1-2 months at typical cafe volumes.
Choose bottled kombucha when
Your primary use case is retail take-home — grab-and-go fridge, grocery shelf, gift packs, hotel mini-bar — or you specifically need flavor variety in small quantities for a low-volume program.
